乙醇是一种可再生燃料，可以从生物质中生产。含45%柴油、45%乙醇和10%丁醇共溶剂的柴油醇（乙醇和柴油）混合物可用作直喷压燃式（DI CI）发动机的燃料，无需任何改性。发现10%丁醇是控制柴油醇共混物相分离的最佳水平。在这项工作中，氧化锌纳米颗粒添加到D45E45B10（45%柴油，45%乙醇和10%丁醇）以三种比例通过超声波处理，以达到均匀的共混物。根据ASTM标准测试了混合物的基本性能，并在CI发动机中以各种负载测试了性能。并与柴油作了比较。结果表明，由于添加了氧化锌纳米颗粒，共混物的能量含量显著提高。氧化锌纳米粒子的催化作用，导致在制动热效率的增加和减少的CO，HC和烟的排放。然而，在额定功率下，氮氧化物的排放量略有增加。纳米氧化锌的加入提高了共混物的缸内压力和放热速率。
Ethanol is a renewable fuel and can be produced from biomass. Diesohol (ethanol and diesel) blends containing 45% diesel, 45% ethanol with 10% butanol as co solvent can be utilized as fuel in a direct injection compression ignition (DI CI) engine without any modification. 10% butanol was found as an optimum level to control phase separation in diesohol blends. In this work, zinc oxide nano particles were added to D45E45B10 (45%diesel, 45% ethanol and 10% butanol) in three proportions by means of ultra-sonication to arrive at a homogeneous blend. Blends were tested for essential properties as per ASTM standards and tested in a CI engine at various loads for performance. The results were compared with diesel. The results showed significant improvement in the energy content of the blends as a result of the addition of zinc oxide nanoparticles.. The catalytic action of zinc oxide nano particles resulted in an increase in brake thermal efficiency and a decrease in the emissions of CO, HC, and smoke. However, there was a slight increase in emissions of NOx at rated power. The in cylinder pressure and the rate of heat release of all the blends were improved by the addition of zinc oxide nano particles.
